I have been using Ubuntu 11.04 on DELL Inspiron 14R (N5010) laptop for last three months. Before I switch to Ubuntu my laptop battery used to give 2.5 hrs to 3 hrs back-up. But since I have been using Ubuntu, it has been reduced to 1hr to 1.5 hrs at max.

Can you supply the output from running: cat /sys/class/power_supply/BAT0/uevent then we can see exactly what the battery is informing the operating system via the ACPI _BST, _BIX (or _BIF) controls. From that we should be able to deduce if the battery is fully charged or if a cell has died.

I'm having a similar issue in which I have installed a new battery that will not charge to it's full capacity. I'm looking for a manner to change some setting in which Ubuntu will allow a full charge, I have a feeling that this has to do with a design in Ubuntu that may be improved upon and is not an issue with Batteries. POWER_SUPPLY_STATUS=Discharging POWER_SUPPLY_PRESENT=1 POWER_SUPPLY_TECHNOLOGY=Li-ion POWER_SUPPLY_CYCLE_COUNT=0 POWER_SUPPLY_VOLTAGE_MIN_DESIGN=23644000 POWER_SUPPLY_VOLTAGE_NOW=23644000 POWER_SUPPLY_CURRENT_NOW=1995000 POWER_SUPPLY_CHARGE_FULL_DESIGN=6000000 POWER_SUPPLY_CH
